Organization Wikis explanation?

Organization Wikis explanation?

When I'm logged in with one of the accounts I created (but not others), on the page https://[xxx].wiki.zoho.com/mywiki.do I see an additional tab called "Organizational Wikis". 

Also the top right menu bar has an item Control Panel, which doesn't seem to work properly -- it pops up a dialog titled Organization Control Panel, which is otherwise empty, and shows a "Loading..." indicator.

I'd appreciate an explanation of what this is all about, as it differs from other accounts.

If it's not applicable to me, I'd also like to know how to revert to an account configuration that works like what other uses see.

Thanks,

- Graham
